Abstract
The utility model relates to a pump head of a combined double-valve style mechanical reciprocating pump. The inner of the pump head is arranged with a water inlet valve and a water discharging valve, a body of the pump head is provided with a water inlet, a water outlet and a plunger hole. The water inlet valve and the water discharging valve are arranged in the same direction and are mutually connected. Cavities provided between the water inlet valve and the water discharging valve and the inner wall of the pump head are alternative cavities. The plunger hole is arranged on the lateral wall of the pump head and is communicated with the alternative cavities. A pressing spring is arranged between a water inlet valve sheet and the water discharging valve, the cavity provided between the water discharging valve and a valve pressing sleeve is a high pressure cavity. The alternative cavities and the high pressure cavity are communicated by a water discharging hole. A spring base is arranged in the high pressure cavity, and the pressing spring is positioned between the spring base and the water discharging valve sheet. The utility model is simple and convenient in mounting, and can effectively raise the efficiency of the pump.
Description
Technical field
The utility model relates to the pump head of a kind of automotive reciprocating pump, particularly automotive reciprocating pump.
Background technique
The feed liquor valve of existing automotive reciprocating pump and liquid discharging valve are installed complicated, and the fluid approach axis is opposite with the discharge direction, has wasted kinetic energy in frequent commutation, has reduced pump efficiency.
The model utility content
For overcoming the above-mentioned defective of prior art, the utility model provides a kind of installation simple and convenient, can effectively improve the automotive reciprocating pump pump head of pump efficiency.
For this reason, the utility model adopts following technological scheme: a kind of combination double-valve formula automotive reciprocating pump pump head, feed liquor valve body and draining valve are housed in pump head body, pump head body is provided with liquid entering hole, liquid port and plunger hole, feed liquor valve body and draining valve are installed in the same way and are coupled to each other, cavity between the two and the pump head body inwall is an alternating cavity, plunger hole is located at the pump head body sidewall and communicates with alternating cavity, between feed liquor valve block and draining valve, holddown spring is housed, cavity between draining valve and the valve gland is a hyperbaric chamber, alternating cavity is communicated with by outage with hyperbaric chamber, is provided with spring seat in the hyperbaric chamber, between spring seat and discharge opeing valve block holddown spring is housed.
Feed liquor valve body and draining valve can link by screw mandrel, also can link by the outside thread projection of feed liquor valve body upper end and the silk hole of draining valve lower end, can also link by the outside thread projection of draining valve lower end and the silk hole of feed liquor valve body upper end.
Between valve gland and the pump head body, between feed liquor valve body and the pump head body and between draining valve and the pump head body seal ring is housed all.
Liquid entering hole and liquid port be uniform setting on pump head body.
Since feed liquor valve body of the present utility model and draining valve in the pump head body of packing into before, connect in advance and make its one-tenth as a whole, reinstall pump head body, with respect to existing automotive reciprocating pump, install simple and conveniently, reduced labor intensity.The discharge opeing direction is consistent with the feed liquor direction during work, flows to constantly in whole motion pressurization, has reduced kinetic energy rejection, has improved pump efficiency.
Description of drawings
Fig. 1 is the utility model embodiment 1 a general structure schematic representation;
Fig. 2 is embodiment 2 a structural representation;
Fig. 3 is embodiment 3 a structural representation.
Embodiment
Embodiment 1: feed liquor valve body 3 and draining valve 6 are housed in pump head body 1, feed liquor valve body 3 and draining valve 6 are installed in the same way and are connected by screw mandrel 18, cavity between the two and the pump head body constitutes alternating cavity 19, plunger hole 17 is located at pump head body 1 sidewall and communicates with alternating cavity 19, at feed liquor valve block 4 and 6 of draining valves holddown spring 5 is housed.By bolt 14 valve gland 13 is housed in pump head body 1 upper end, cavity between draining valve 6 and the valve gland 13 constitutes hyperbaric chamber 10, alternating cavity 19 is communicated with by outage 20 with hyperbaric chamber 10, bolt 12 is contained on the draining valve 6, spring seat 11 is housed above it, and 8 of spring seat 11 and discharge opeing valve blocks are equipped with holddown spring 9.For improving the sealability between each parts of pump head, at feed liquor valve body and pump head body junction sealing gasket 2 is housed, in addition, O RunddichtringO 7 all is housed at valve gland, feed liquor valve body and draining valve and pump head body inwall junction.
During installation, feed liquor valve body 3 and draining valve 6 usefulness screw mandrels 18 are linked together, pack into before connection holddown spring 5 and feed liquor valve block 4 connect and feed liquor valve body 3 and draining valve 6 are together packed in the pump head body after good, load onto the valve gland and compress and get final product.During use, liquid enters alternating cavity 19 from the inlet opening 16 of liquid entering hole 15 on feed liquor valve body 3, and after the supercharging, outage 20 enters hyperbaric chamber 10 after liquid port 21 effluxes on draining valve 6 in the to-and-fro motion of plunger.Liquid flows to constant in whole motion pressurization, has reduced kinetic energy rejection, has improved pump efficiency.
Embodiment 2: substantially the same manner as Example 1.Different is that feed liquor valve body 3 links by the outside thread projection 22 of feed liquor valve body upper end and the silk hole 23 of draining valve lower end with draining valve 6.
Embodiment 3: substantially the same manner as Example 1.Different is that feed liquor valve body 3 links by the outside thread projection 24 of draining valve lower end and the silk hole 25 of feed liquor valve body upper end with draining valve 6.
